1. Greedy Algorithm: A greedy algorithm is an algorithmic strategy where the optimal solution is chosen at each step in order to maximize an objective function. 

2. Gradient Descent: Gradient descent is an iterative algorithm which seeks to find a minimum by following the steepest descent from a given point.

3. Simulated Annealing: Simulated annealing is a metaheuristic algorithm to find an approximate global optimum for a given objective function. 

4. Genetic Algorithm: A genetic algorithm uses evolutionary concepts such as mutation, selection, and crossover to sample solutions in search for a global optimum. 

5. Branch and Bound: Branch and bound is an algorithmic technique which consists of dividing the problem into subproblems and bounding the solution space to guarantee an optimal solution.
